New graphics card, old motherboard

Will a 1Gb Radeon HD7770 be able to replace a 512Mb Radeon HD 4850 which is now 4+ years old? Will it be quieter and fit into my Asus P6T Deluxe motherboard? Thank you.

<<Will a 1Gb Radeon HD7770 be able to replace a 512Mb Radeon HD 4850 which is now 4+ years old?>>

Yes, provided your system has minimum 500W (or greater) power supply with one 75W 6-pin PCI Express power connector.

<<Will it be quieter>>

Not sure but I know that the HD48xx series is quite noisy (sometimes like a jet is taking off) ,let's hope the HD7770 runs quieter.

<<and fit into my Asus P6T Deluxe motherboard?>>

Yes, it'll fit into your socket 1366 board without problem but as I said please check the PSU power output.

The system has a 600W power supply and has 3PCI Express 2.0 x 16 slots, 1 PCI Express x 4 slot and 2 PCI slots so I hope that covers it. The HD4850 is noisy at the minimum 6% and even my inept playing of Skyrim makes it whine like Concord-The Return. Thanks.

And here I thought this would be easy. Perhaps I should tackle this from another angle? I want to change the HD4850 because it is too noisy and takes too much power. The new card must be quiet, use less power and fit into my current motherboard without any other changes. I want it to be able to facilitate a full hd monitor with great graphics and for the occasional game. I would like to stick with asus but I need help with the best choice. Thanks

1.What is your budget?

2.What size & resolution of HD monitor have you got?

3.What occasional games do you play?

Budget up to £90. I am going to buy a iiyama X2377HDS ProLite 23 inch Full HD LCD Monitor with LED Backlight (1920 x1080, 1000:1, 5ms, 250cd/m2) and Skyrim was the last game played, although the noise level is the most important factor. The hd7750 should be able to fit without any extras and I have read that pcie3 is backwards compatible with my pcie2 but I don't know what you lose if that connection is made?

To be honest with your budget, I think you can't beat the price/performance of the HD7770 with other equivalent priced Nvidia cards & it handles Skyrim & other similar games with ease. Here are some examples from ebuyer. com click here , reviews didn't say much about noise problem & it draws 75W only compares to the HD4850's 140W.

You won't lose anything if that connection is made & won't see much difference even if your motherboard supports PCIe 3.0.
